We describe a new species of egg-eating sea snake, Aipysurus mosaicus sp. nov., from northern Australia and southernNew Guinea. This species was previously considered to be an allopatric population of A. eydouxii, which occursthroughout the Sunda Shelf and in New Guinea. Molecular analyses reveal these two species to be sister lineages withfixed nucleotide substitutions at three independent mitochondrial and nuclear loci, and a deep phylogenetic divergenceexceeding that of all other sampled species pairs in Aipysurus. Aipysurus mosaicus sp. nov. is also distinguished from A.eydouxii by morphological characters relating to scalation (e.g. number of ventral scales), colour pattern (e.g. number andshape of transverse body bands), internal soft anatomy (e.g. position of heart in relation to ventral scales), and skeletalmorphology (e.g. shape of nasal and caudal neural spines). Additional sampling is needed to clarify the extent ofgeographic contact between A. eydouxii and the new species in New Guinea where they appear to be sympatric. It is likelythat the boundaries between these taxa will be mirrored in other coastal sea snakes with ranges spanning the deep watersof the Timor Trench; discovery of such cryptic species will have important implications for conservation of this highly diverse but relatively poorly studied group of marine vertebrates.

A new species of viviparous sea snake, Hydrophis donaldi sp. nov. (Hydrophiinae), is described from the Gulf of Carpen-taria, northern Australia. Molecular analyses reveal this species as a deeply divergent lineage within the Hydrophis sub-group, and separate it from all other sampled taxa by fixed nucleotide substitutions at three independent mitochondrial andnuclear loci. The new species is assigned to Hydrophis based on the current morphological diagnosis of this large but pa-raphyletic genus, and is distinguished from all other Hydrophis species and closely allied genera by a combination of mor-phological characters relating to scalation, colour pattern and osteology. Using current keys for sea snakes, H. donaldi sp.nov. might be mistaken for H. coggeri, H. sibauensis or H. torquatus diadema but it is readily distinguished from thesespecies by a higher number of bands on the body and tail, lower ventral count, strongly spinous body scales, and a wider,more rounded head. Sea snakes have been sampled intensively in the Gulf of Carpentaria due to their vulnerability to by-catch in the region’s commercial prawn-trawl fisheries. That this highly distinctive new species has evaded discovery inthe region until now is surprising, but might be explained by its habitat preferences. All known specimens of H. donaldi sp. nov. were found in estuarine habitats that are relatively poorly surveyed and are not targeted by commercial fisheries.

We describe a new species of groundsnake of the genus Stegonotus (Colubridae) from the Purari River basin in Gulf Province, Papua New Guinea. The new species can be most readily distinguished from all other New Guinean Stegonotus by its unique dorsal colour pattern which consists of a dark head and creamy-white anterior one third to two thirds of the body, grading into increasingly dense dark pigmentation on the posterior of the body and tail. It is most similar to S. iridis from the Raja Ampat Archipelago off western New Guinea, but that species has a different pattern of pigmentation dorsally, has a lower ventral scale count (198–211 vs. 229–239), and exhibits a different temporal scale arrangement. The description of S. aplini sp. nov. brings to fourteen the number of Stegonotus species described from New Guinea. A dichotomous key to described species in the New Guinea region is provided.

Paracobitis salihae, new species, from the Göksu River in the western upper Euphrates drainage, is distinguished from other Paracobitis species by possessing a truncate caudal-fin, and a dark-brown vermiculate or marbled colour pattern. It is also characterised by 19 variable nucleotide substitutions, three diagnostic nucleotides and 3.6% minimum K2P distance compared to geographically adjacent and related P. zabgawraensis. Paracobitis salihae might be Critically Endangered and is threatened by dam constructions.

AbstractA new species, Chaoborus sampsera, is described from male and female adults collected from Papua Province in western New Guinea, Indonesia. Based on leg banding, wing pigmentation, and possession of a median paramere sclerite in males, the new species belongs to the Chaoborus “pallidus” group of Colless. Chaoborus sampsera is distinguished from other species of the “pallidus” group by the scimitar-shaped parameres. Although relationships among these Chaoborus species are unclear, there are morphological characters that support the “pallidus” group.

A new species of betel nut palm, Areca jokowi, is described and illustrated here. This is the third species of Areca to have been described recently from New Guinea that is closely related to the widespread, economically important species A. catechu, the cultivated betel nut palm. A discussion of its morphological characters, distribution, ecology, habitat, uses and conservation status is provided, as well as a new identification key for western New Guinean Areca.

We describe a new species of turtle-headed sea snake Emydocephalus orarius sp. nov. (Elapidae) from Western Australia’s Coral Coast, Pilbara and Kimberley regions. Phylogenetic analysis of mitochondrial markers places the new species as the sister lineage to the two currently recognised species in Emydocephalus: E. annulatus from the Timor Sea reefs and Coral Sea, and E. ijimae from the Ryukyu Islands. Analysis of nuclear SNP data from the new species and E. annulatus from Australia and New Caledonia provides additional independent evidence of their evolutionary distinctiveness. The new taxon is usually morphologically diagnosable from its congeners using a combination of scalation and colour pattern characters, and appears to reach greater total lengths (>1 m in the new species versus typically ~80 cm in E. annulatus/E. ijimae). The new species is known largely from soft-bottomed trawl grounds, unlike E. annulatus and E.ijimae which usually inhabit coral reefs. The discovery of this new species brings the number of sea snake species endemic to Western Australia to six.

A new species of catshark, provisionally placed in the genus Galeus, is described from Papua New Guinea based on 7 specimens collected during recent deepwater surveys of the region. The new species, Galeus corriganae, is closest to G. priapus from New Caledonia and G. gracilis from northwestern Australia but differs in several morphological characters. A reclassification of the catshark groups is required to revise the familial and generic arrangement of the group.

A new species of pomacentrid fish is described from coral reefs of Papua New Guinea. Specimens were collected by the author between 1982 and 2000. Pomacentrus aurifrons is described from 12 specimens, 22.4 61.5 mm SL, collected at depths between 7 12 m. It closely resembles P. smithi Fowler and Bean from Indonesia and the Philippines. These species have similar morphology but are easily distinguished by the taller dorsal fin of P. aurifrons (tallest dorsal ray averaging 1.37 in HL versus 1.65 in HL for P. smithi) and colour pattern differences, particularly the broad zone of yellow encompassing the snout, forehead, and base of the anterior dorsal spines.

A new species of the currently monotypic genus Fenerbahce is described from the eastern Congo Basin. It is distinguished from F. formosus from the western Congo Basin by several characters, of which the most prominent are: a more anterior origin of dorsal fin relative to anal fin, a deeper body, long extension on edges of the caudal fin, and a distinct colour pattern. The distinctness of the two species is supported by additional morphological characters and the results of a preliminary analysis of mitochondrial and nuclear DNA sequences.
